Meta Software Engineer interview questions

I had a technical phone interview where I shared a little about myself with the interviewer from California. Then we did one interview question, which I coded on an online notepad and talked it over on the phone. Then I asked 2 questions and awaited for the result. It was a good experience even though I did not get an offer.

Applied through internal referral. Got notified about interview in less than three days. Scheduled interview a few weeks later. Had phone interview with an engineer. The interviewer was friendly and gave hints whennI was stuck. Was asked a lot of time complexity questions.
